Ink scraping structure of oil printing equipment

Abstract

The invention provides an ink scraping structure of oil printing equipment. The ink scraping structure aims to solve the problem that when an existing ink scraping structure of the oil printing equipment is used, ink brought to a main scraping knife by a roller is large in amount and prone to accumulating and dripping, so that the completeness of ink staining of the roller is affected. The ink scraping structure comprises an ink disc, a roller and a main scraping knife, wherein the ink disc is used for containing ink, part of the roller is soaked into the ink disc, and the main scraping knife is matched with the roller. The ink scraping structure is further provided with a lower scraping knife, the middle of the lower scraping knife is fixedly connected to the inner wall of the ink disc, the upper end of the lower scraping knife is attached to the roller, and the lower end of the lower scraping knife is soaked in the ink inside the ink disc. The ink scraping angle of the lower scraping knife ranges from zero to ten degrees. The upper end of the lower scraping knife is attached to the roller and provided with an arc-shaped groove deviating from the roller. The end of the main scraping knife is connected with an auxiliary scraping knife made of rubber, and the head of the auxiliary scraping knife is provided with an arc-shaped face matched with the roller, and attached to the roller in a pressed mode. The ink scraping structure has the advantages that ink dripping is avoided, the liquid level of the ink is stable, ink staining of the roller is complete, and printed characters or patterns are complete and clear.

Description

technical field [0001] The invention relates to the technical field of printing industry, in particular to a scraping structure of mimeograph equipment. Background technique [0002] In the scraping structure of the existing mimeograph equipment, the main scraper is set close to the upper end of the roller, and the distance from the ink liquid level is higher. Excessive ink picked up by the roller from the ink tray will scrape off the roller at the main scraper and accumulate droplets. Falling back into the ink tray, this makes the ink liquid level unstable and fluctuates, and the ink attached to the position just turned out of the ink liquid surface on the roller will be stained again and flow back into the ink tray, resulting in incomplete ink staining of the roller , the printed pattern or text is incomplete. [0003] For example, in the existing public documents, there is a Chinese patent document with the announcement number CN201587173U and the announcement date of 20...
